HOW TO MEASURE BRA SIZE?
How Do Bra Size Work?
Bra sizes are based on your band size (the number) and your cup size (the letter). These measurements are usually determined by using a tape measure around your rib cage and bust. The number/letter is your bra size. Finding the right bra size is crucial for the right support and for a smooth comfortable fit. To all the girls and women who have worn an ill-fitting bra or wrong bra size know that this can ruin a great outfit and even worse the entire day with backaches and pain.
The number or the 'band size' is a representation of your rib cage girth. We get this size by taking a measurement around your rib cage, about where the bra band sits. This measurement is taken in inches. As mentioned, this number gives us a guide to what size bra we need to accommodate the circumference of your rib cage, overlying skin and subcutaneous tissue.
The letter component is an indication of cup volume. The amount of actual breast tissue/fat in volume.
Understanding this is where the magic will happen for you when out bra shopping solo. Have you heard of sister sizing? That's what all of this is about... The band size will dictate how much cup volume your 'cup size' has.
Step-by-Step Guide to Measure Your Bra Size
An accurate way to measure your bra size is with a measuring tape, that doesn’t mean you can’t figure out your correct bra size without one! It’s actually pretty easy to measure your correct bra size without a measuring tape, as long as you have an existing bra for reference.
You can use our Sizing Guide tool to help you learn your bra size without a tape measure so you can find the perfect bra fit straight away, or you can follow this guide to work your bra size out yourself.
Lots of us are wearing the wrong size, which means we don't look or feel as good as we should! Follow below to make sure you've got both your band and cup sizes just right.
If your band is too big or small but the cup is just right, you need to move up or down a band size and move your cup size to your sister size. A sister size is the equivalent cup size on a different band length. When you move up a band size, you move down a cup size, and if you move down a band size you move up a cup size (provided the same cup size is needed). For example, a 32B is equivalent in terms of cup size to a 34A or a 30C.
